SuperPro 2011 Subaru Impreza WRX STI Front Lower Inner DuroBall Control Arm Bushing Kit (+Caster) 3.3 lb

Control arm bushings form the vital pivot and link between all core suspension components. SuperPro increases the performance and precision over traditional elastomer bushings with the compound DuroBall bushing assembly. Using an isolated spherical bearing encased in polyurethane provides the precision and articulation of a bearing design with the NVH mitigation of SuperPro's bespoke polyurethane compositions SuperPro's 'offset' bushing options introduce additional positive caster into the front end suspension geometry. With a small but significant change the additional caster delivers several benefits: Improved straight-line stability and tracking; your vehicle will track straight and return to center with less driver input. Dynamic camber gain with steering angle “ the more your turn the wheel with additional caster the more both wheels will ˜camber' into the turn putting more of the tire's contact patch on the road as the suspension loads up in the corner and helping to resist the tire ˜rolling over' onto the shoulder and compromising grip. Enhanced steering weight and feel; the small caster change will weight up the steering slightly as you come off-center and the improved cornering grip delivers greater feel for the handling limit through the wheel. The caster offset bushings deliver only benefits with no negative impact on tire wear, comfort or unwanted handling behavior. SuperPro's polyurethane bushings are the culmination of nearly 5 decades of suspension expertise and development in Australia's harshest terrain. Designed with durability as a paramount feature we also bring ride and passenger comfort to the forefront of our development. Our designs and material compositions retain OEM levels of noise and harshness isolation while delivering superior performance and road manners in all conditions.
